(cvs.info)Assigning revisions


Assigning revisions
===================

   By default, CVS will assign numeric revisions by leaving the first
number the same and incrementing the second number.  For example,
`1.1', `1.2', `1.3', etc.

   When adding a new file, the second number will always be one and the
first number will equal the highest first number of any file in that
directory.  For example, the current directory contains files whose
highest numbered revisions are `1.7', `3.1', and `4.12', then an added
file will be given the numeric revision `4.1'.

   Normally there is no reason to care about the revision numbers--it
is easier to treat them as internal numbers that CVS maintains, and tags
provide a better way to distinguish between things like release 1
versus release 2 of your product (Note: Tags).  However, if you want
to set the numeric revisions, the `-r' option to `cvs commit' can do
that.  The `-r' option implies the `-f' option, in the sense that it
causes the files to be committed even if they are not modified.

   For example, to bring all your files up to revision 3.0 (including
those that haven't changed), you might invoke:

     $ cvs commit -r 3.0

   Note that the number you specify with `-r' must be larger than any
existing revision number.  That is, if revision 3.0 exists, you cannot
`cvs commit -r 1.3'.  If you want to maintain several releases in
parallel, you need to use a branch (Note: Branching and merging).
